Table 19. Port A–B Alternate Function 0 Sub-Registers
Table 20. Port A–C Output Control Sub-Registers
Port A–C Output Control Subregisters
The Port A–C Output Control subregisters, shown in Table 20, are accessed through the
Port A–C Control registers by writing
bits in the Port A–C Output Control subregisters to 1 configures the specified port pins for
open-drain operation. These subregisters affect the pins directly and, as a result, alternate
functions are also affected.
